consider the following code:
public abstract class MachineInPitImpl extends AbstractPersistentObject implements MachineInPit {
protected PersonReference currentOperatorRef;
public void setCurrentOperatorRef(PersonReference currentOperatorRef) {
this.currentOperatorRef = currentOperatorRef;
this.currentOperatorObj = null;
}
public PersonReference getCurrentOperatorRef() {
return currentOperatorRef;
}
The above class is not wired with spring context, I need to extend this class and grab the values in the get method of this class in my new class. I have wrote a class as this:
public class MachineOPJMXBeanImpl extends MachineInPitImpl {
public MachineOPJMXBeanImpl(){
}
@Override
public PersonReference getCurrentOperatorRef() {
return super.getCurrentOperatorRef();
}
}
But the value in this class get method is null.Why am I getting null value? Here is the applicationcontext.xml file:
<bean id="machineOPJMXBean"
class="com.mincom.works.cc.personnel.node.MachineOPJMXBeanImpl" parent="machineInPitImpl">
<property name="currentOperatorRef" ref="currentOperatorRef"/>
</bean>
<bean id="machineInPitImpl" class="minestar.pitlink.domain.pitmodel.MachineInPitImpl" abstract="true" scope="singleton" lazy-init="true">
<property name="currentOperatorRef" ref="currentOperatorRef"/>
</bean>
<bean id="currentOperatorRef" class="minestar.machinetracking.domain.PersonReference"/>
